Microsmart controllers not following commands from a Niagara R2 schedule

Issue

Microsmart controllers not following commands from a Niagara R2 schedule

Environment

Niagara R2 (all versions)

Microsmart controllers (all versions)

Cause

Power failure in building

The UNC does a 'graceful' shutdown, using its backup battery, 60 seconds after main AC power is lost.  If the power failure in the building lasts less than 60 seconds, the Microsmart controllers come back online.  The UNC never shuts down and thinks the Microsmart controllers are online.  Meanwhile the Microsmart shadow objects in the station are no longer updating.  The link between them and the points in the Microsmart was lost (during the power failure) and does not automatically recover.

Resolution

Reboot the UNC
